Gene Details:

• MSU gene ID: LOC_Os06g39590
• RAPdb gene ID: Os06g0597000
• Gene Symbol: OsIAA23
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Expression of OsIAA23 is specific to the QC of the root tip during the development of primary, lateral and crown roots.
• Consistent with OsIAA23 expression in the QC, the auxin signaling marked by DR5p::GUS (ss-glucuronidase) was absent in the QC region of OsIAA23.
• These results indicate that the maintenance of the QC is dependent on OsIAA23-mediated auxin signaling in the QC.
• OsIAA23-mediated auxin signaling defines postembryonic maintenance of QC in rice.
• The mutant is characterized by a loss of QC identity during postembryonic development, and the displayed defects result from a stabilizing mutation in domain II of OsIAA23 (Os06g39590).
• Transgenic rice plants harboring OsIAA23 under the control of the QHB promoter mimic partially the defects of OsIAA23.
• In rice, the gene OsIAA23 (Os06t0597000) is known to affect development of roots and shoots, but previous knockouts in OsIAA23 have been sterile and difficult for research continuously.
